[Vwdiesel] Anyone try this? (To have a warm, toasty car)

Hmm, well my goal is not really to be able to start the car (it is a gasser so not much of a worry there really) but to just have the interior warm as quickly as possible.  I'm in Manhattan Kansas, so it doesn't get super super cold, but I'm kinda wimpy when it comes to cold.  ;)

Sounds like the best thing is just have the engine toasty  with the heater and call it good.
